I was always rather fond of EBTG's "Missing" especially in my lovesick teenagery days... glad to see that one made it up there.

The CD's I wore out from overplaying (well, the first was a cassette) were Enigma's MCMXC, Ace of Base's The Sign, Nirvana's Nevermind, NIN's The Downward Spiral, Duncan Sheik's self-titled album, and Robert Miles' Dreamland.
